● Dual Sealing Structure: Equipped with a double-gate design, each gate features an independent sealing system to completely isolate the medium during sampling, eliminating the risk of leakage.
● Bidirectional Sealing Function: The valve provides sealing in both forward and reverse directions, effectively preventing backflow of the medium and ensuring the accuracy and safety of sampling.
● High Corrosion Resistance: The valve body and key components are made of high-quality corrosion-resistant materials, suitable for various acidic and alkaline media environments, extending service life.
● Easy Operation: Available with manual or electric actuation, the valve offers flexible operation and can quickly complete sampling tasks, improving work efficiency.
● Precise Sampling: The valve design ensures stable sampling flow, avoiding media fluctuations and meeting high-precision sampling requirements.
● Convenient Maintenance: With a compact structure that is easy to disassemble and maintain, it reduces maintenance costs and downtime.
● The Double Gate Sampling Valve is widely used in industries such as chemical, pharmaceutical, and food, making it an ideal choice for safe and efficient sampling.

Forged steel globe valve is a high-performance fluid control equipment, manufactured with high-quality forged steel materials and precision, integrating throttling and shut-off functions. Specially designed for high-pressure and high-temperature working conditions, it has the characteristics of compact structure, reliable sealing, and long service life, and is widely used in harsh working conditions in industries such as petroleum, chemical, and power.
Designed specifically for industrial ventilation and gas transportation systems, it features a high-strength carbon steel or stainless steel valve body, equipped with a low-torque sealing structure, enabling efficient regulation of large flow of gas media. The optimized butterfly plate design is combined with wear-resistant sealing rings, ensuring reliable performance under harsh conditions such as high temperatures and dust. It is suitable for ventilation and dust removal systems in industries such as power plants, metallurgy, and chemical engineering
The globe valve is mainly composed of valve body, valve cover, valve disc and valve stem. The handwheel applies a certain torque at the upper end of the valve stem. The valve stem is passed to the valve petals through the valve stem, so that it moves up and down along the valve stem axis to achieve fully turned on or fully closed movements. The force applied by the handwheel acts on the disc to hold it against the seat to seal. The single disc globe valve is designed to enter the medium by the valve disc sealing surface below, the medium force is opposite to the direction of valve closing, so the valve closing torque is large, so the single disc globe valve is mainly used in low pressure or small diameter pipelines. At the same time, the globe valve does not rub with the valve seat before the valve is closed, thereby reducing the wear of the cover surface and effectively extending the service life of the valve.
